Oh lordy, this was absolutely wonderful!!! I find that I'm getting addicted to Uther/Merlin, and this was an awesome take on their... er... sexual escapades? Gah, I love the pain and shame and pleasure and the addiction they seem to have to each other and THE COLLAR and the submissiveness of Merlin and Uther whispering to him not to move and gaaaah, it was sexy. I loved this. A lot.
